Hackers have attacked three websites belonging to Yogyakarta Police after taking repressive measures against Papuan students staging a peaceful rally at a Papuan students dormitory in Kamasan, Yogyakarta, last Friday.

“We cannot conclude if this is part of a reaction [to the police’s handling of the protest], but we are still investigating those responsible,” Yogyakarta Police spokesperson Adj. Sr. Comr. Anny Pudjiastuti told The Jakarta Post on Monday.

As of noon Monday, two sites — jogja.polri.go.id and tribatranewsjogja.com — had already been recovered. The third site, polresjogja.com was still paralyzed where its front page read: “Why so serious, introduce a little anarchy and everything becomes chaos. Great, you’ve shown us how justice works. Improve your brutality, Sir. Ps We’reNotSeparatists# GretzTomcat-Rebels-Tanpa Bicara-Virusa.”
